Same old thing. Even if you can fork successfully will there be a project that will be created under this fork?
You'd have a hard time, the only that is supported is the ETC and even them are having some hard time. There are only few projects with ETC today though I have no doubt there will be more in the coming years but its a slow progress just like the adoption. There are newer platforms that is competing them directly that will make it more difficult for these forks.
